Abstract
We report the observation of oscillatory redox reactions on the surface of multilayer graphene oxide (GO) films at room temperature. The redox reactions exhibited dampened oscillatory behavior with a period of about 5 days and were found to be dependent on the time elapsed from film deposition. The kinetic behavior observed for the oxidation-reduction reactions and the metastability of the surface functional groups are adequately described by two models involving GO reactions and reactant diffusion.
